The phenomenal success of atomic force microscopy (AFM) in industry is base
d on the easy access of samples with practical interest due to the high res
olution and high contrast of the method under controllable ambient conditio
ns. In our case, the high resolution of AFM is mainly used in the mesoscale
range. The high contrast using tapping mode AFM provides information for u
nderstanding morphological features of soft organic material such as polyme
rs and coatings and also for hard metallic and ceramic systems. But for cor
relation of the observed morphology with chemical species the combined use
to AFM and transmission electron microscopy often is necessary. As an examp
le elucidation of the morphology of thermoplastic polyurethane will be disc
ussed in more detail. Copyright (C) 1999 John Wiley & Sons, Ltd.
